Recent forecast models from Environment Canada and others show Toronto's September 20 minimum likely falling near 7–12°C amid northeasterly flow, increasing cloud cover, and a 30% shower chance, creating the near-even split between sub-8°C and 18°C+ outcomes. Radiative cooling under clearer skies could drive the lowest readings toward single digits, while persistent low clouds and moisture limit overnight temperature drops; model divergence on exact cloud timing and wind speeds near 10–15 km/h explains the tight clustering around 9–17°C probabilities. Updated runs ahead of the weekend will clarify whether a stronger cool advection or lingering marine influence shifts the minimum.

The resolution source for this market will be information from NOAA, specifically the lowest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=cyyz
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
